Unicorn Bottle – What is it in Vaping?
Definition
A Unicorn Bottle is a slim, flexible, 30 mL or 60 mL plastic e-liquid container fitted with a long, needle-tip nozzle. Designed for mess-free refilling, it replaces the original glass dropper bottles that come with most vape juices. The soft PET or LDPE walls let you squeeze precisely, making it easy to top up tanks, pods, or drippers without spills. Compact enough to slip into a pocket, it is the go-to accessory for Australian vapers who want portability, convenience, and clean handling of nicotine e-liquids.
Technical Details
Unicorn Bottles are blow-moulded from food-grade, BPA-free PET or LDPE, giving them a shatter-proof, squeezable body. Standard capacities are 15 mL, 30 mL and 60 mL; the 30 mL size measures 18 mm diameter × 95 mm tall and weighs 8 g empty. The 1.5 mm bore needle tip accepts 510-threaded caps, child-resistant CRC caps, or twist-off tops, and creates a controlled 0.05 mL micro-drop. Wall thickness is 0.4 mm, allowing 30–40 compression cycles before material fatigue. Variations include opaque bottles for nicotine salt stability, PET with UV blockers, and chubby-gorilla style with wider 20 mm necks for faster filling machines. Heat tolerance peaks at 60 °C; beyond this, plasticisers may leach, so they are not suited for hot-fill processes.
Usage & Tips
Before first use, rinse with warm water and air-dry to remove manufacturing dust. When transferring e-liquid, insert the needle tip against the tank wall to prevent air locks. Leave 5 % headspace to allow for vacuum expansion during flights. If the tip clogs with sweetener crystals, snip 2 mm from the end or flush with warm PG. Store upright and out of sunlight; prolonged UV exposure can warp the plastic and fade labels. Always replace the cap firmly—child-resistant caps must click twice to comply with Australian poison-control standards. Label each bottle with flavour, strength, and mix date to avoid confusion.
History & Context
Unicorn Bottles debuted in the U.S. around 2014 when high-VG e-liquids proved too thick for traditional droppers. Their pocket-friendly shape quickly made them the default for cloud-chasers and later for ultra-portable pod users. Today, virtually every Australian e-liquid brand ships 30 mL nic salts in Unicorn Bottles to meet TGO 110 labelling rules while keeping prices low.
